Imagine having hundreds of websites linking to your website and promoting your product or service. Sounds nice huh? Now imagine not having to pay a cent for advertising unless you actually generate sales through your affiliates. Sounds even better right?

Now all you need to do is figure out how to set-up an affiliate program. There are lots of great services and software programs that will allow you to do so. When creating an affiliate program, you can go one of two ways: you can join a "network" of affiliate programs which will administer the tracking of sales or click-thru's for your program. The down-side of joining a network is they charge 30%-50% of the original amount you are offering as a commission for themselves. The up-side of joining a network is they can help you find many more affiliates to help promote your product or service, and they will issue checks to the affiliates themselves which would save you a lot of time.

Here's a few excellent affiliate program networks:
